Installing solar panels on concrete tile roof

One of the most important decisions you will make when installing solar panels is choosing where the equipment will be placed on your home or property. Of course, you want to minimize the appearance of these panels so they don’t affect your curb appeal. At the same time, it’s crucial to ensure that you are getting the optimal amount of sunlight exposure throughout the day.

Installing Solar Panels on the Roof

The roof is one of the most common places to install solar panels. But this installation process depends on the type of roofing materials that are on your home. Placing the panels on the roof is an excellent strategy because you minimize the shadows and other elements that could block sunlight from the solar panels.

For example, unique challenges need to be addressed if you have a tile roof. Of course, it’s possible to install the panels on tile roofing materials. Still, you’ll want to talk to an experienced team about the best installation strategies to protect the quality of your roof.

Mounting Solutions for All Tile Roof Types

A professional solar panel installation team can assist with mounting solutions for all types of tile roofs, including:

• Spanish tile roofs
• Clay tile roofs
• Concrete tile roofs

These tiles tend to be fragile, which is why it’s essential to ask the installation team about the measures they are taking to protect the tiles.

Tips for Solar Panel Installation on a Tile Roof

Here are a few tips to minimize damage to your tile roof:

• Tread Carefully: The tiles can be damaged by walking on them, so the installation team is careful about stepping on the right part of the tile to reduce the risk of cracking.
• Spare Tiles: It’s likely that some of the tiles will break, even if the installation team is gentle with their movements. A smart move is to have extra roofing tiles handy in case tiles need to be replaced during the installation.
• Roofing Adjustments: Instead of placing the solar panels on the tiles, you might consider putting shingles in the places where the panels are being installed. It’s easier to mount these panels on a shingled roof, and you won’t be able to see the difference since the solar panels will hide the shingles.

The best roofs for solar panels: what are the different roof types you can install solar panels on?

Solar can be installed on almost any roof – here are some of the most commonly used roof materials that solar installers will encounter on the job:

• Asphalt shingles
• Clay tiles
• Slate tiles
• Concrete
• Rubber
• Wood
• Metal

While solar panels can usually be safely and effectively installed on all of the above roof materials, the exact installation processes may differ. As such, there is no “best” roof for solar – panels can go on just about any roof material. Below, we’ll look at each of the various roof materials and how installers secure solar panels to each.

Installing solar panels on tile and shingle roofs

Many properties have a tiled roof, which may seem like a barrier to installing solar. However, solar racking companies and installers have crafted many smart and safe ways to make putting solar panels on a tiled or singled roof easy.

Can you install solar panels on asphalt shingle roofs?

Asphalt is perhaps the most popular roof material – as such, asphalt shingle solar panel installations are common and straightforward. Installers will drill studs into your roof and attach panel mounts at those locations. The space around the brackets is both sealed and surrounded with a flashing – a metal plate used to prevent water infiltration – to finish the job.

Can you install solar panels on clay tile roofs?

Traditional Spanish tile roofs are made from clay tiles – this can be a pricey material to install solar panels on given the extra labor required, but it’s still very doable for solar installers.

Unlike traditional asphalt roofing, clay tiles are usually removed and replaced during a solar installation. This is for two reasons: first, clay tiles are relatively fragile and may break when installers walk on your roof. Second, in order to properly secure your solar panels, your installer needs to bolt the feet of your solar racking equipment directly to your roof. With clay tile roofs, this area can only be accessed properly by lifting tiles up.

As such, to properly anchor your solar panel racking, solar installers will typically remove clay tiles at the areas where they need to attach racking feet to your roof. Metal hooks and flashing are drilled into the roof, and your tiles can be slid back into place above the mounting feet. Depending on the exact shape and dimensions of the clay tiles on your specific roof, your installer may need to purchase or make uniquely-shaped hooks and flashing so that they fit fasten properly under the tiles. Companies like SnapNrack make specialized mounting inserts for all types of tiles.

In some cases, installers might simply replace the original tile with a new metal version, essentially combining the tile, mounting foot, and flashing into one piece of equipment.

Can you install solar panels on slate and concrete tile roofs?

There’s more work involved than with asphalt tiles, but solar panels work just fine on slate and concrete tile roofs. Much like clay tiles, both slate and concrete tiles are usually removed and replaced during the solar panel installation process. In some cases, installers will drill through the tiles themselves, but it’s more common to remove the tiles and replace them with a mounting foot and flashing because of the brittleness of slate and concrete.

Not all roofs are made of tiles. In this section, we’ll talk about how solar panels are installed on other common roof materials such as concrete, rubber, and wood.

Can you install solar panels on flat concrete and rubber roofs?

Some homes (often multifamily or commercial buildings) are topped with a flat concrete or rubber roof. Fortunately, you can still install a solar panel system safely and effectively on both. With a flat roof, panels need to be tilted towards the sun for optimal production, so your solar installer will need to install slanted metal racking to prop up your panels. Often times these systems don’t even need to be attached to your roof – many flat roof installations utilize a ballast system instead of standard penetration mounting that slanted residential roofs usually need. Ballast systems are simply a weighted racking setup that holds solar panels in place.

On the off chance that you need to drill into your flat roof to install solar panels, don’t worry – your solar installer will make sure that the holes they drill are as small as possible and sealed properly to avoid any roof damage or leaking.

Can you install solar panels on wooden roofs?

Similar to asphalt shingles, installing solar panels on a wood or cedar roof mainly consists of drilling into a roof stud and slipping flashing in under the wood pieces to prevent leaking. Wood shingling can be brittle, and your installer will need to take extra precautions when mounting your panels to ensure that no parts of your roof end up unnecessarily cracked or damaged in any way.

Can you install solar panels on metal roofs?

Depending on the type of metal roof you have, installations will differ slightly, but the big takeaway is that solar panels work well on metal roofs. If you have a standing seam metal roof, your solar installer won’t even have to drill holes in your roof, as panel mounts can simply be clamped to the raised seams. If you’re working with a corrugated metal roof, your installer will need to drill holes into the roof. This won’t damage your roof – just like asphalt tile or other common roof types, waterproofing sealant prevents any moisture from getting through over the lifetime of your solar panel system.

Solar panels work on many different property and roof types

Regardless of what kind of roof is over your head – tiled, flat, wooden, and others – a solar energy installation can help you save money on electricity bills. Especially with unique roof materials and shapes, it’s always a good idea to get multiple quotes from reputable, experienced installers. The best way to find and compare quotes from solar companies near you is by registering your property on the EnergySage Solar Marketplace. When you join, you’ll indicate the location of your property on satellite imagery so that installers can provide custom quotes given the size and material of your roof. You can also leave a note in your profile indicating your roof material type after joining.
